Authorities said police responded to a 911 call at 3:41 p.m. about a 4-month-old baby who wasn't breathing.

Investigators said Phillips slammed his 3-month-old child on the floor inside his residence.

Officers said the baby was taken to Children’s Hospital and is in critical condition.

"Supposedly the baby was found blue. (The mother) down to another neighbor’s house and from there someone tried to give her, the baby CPR and then blood started running out of the baby’s nose and from there 911 was called," Casey Donnelly, who is a neighbor, said.

Officials said the mother was at the library with a friend when the incident happened.
